Logique Mathématique - Implication - La Logique - 1 Bac SM S.EX [Exercice 1]

In this video, I'll be working with you to correct an exercise from the chapter "Mathematical Logic," in which we'll demonstrate implication or "direct reasoning." This video is intended for first-year baccalaureate students (Science, Mathematics, and Science). 💡Remember, it's important to try to work through the exercise before seeing the answer key. ▬▬▬▬▬▬▬▬▬▬▬▬ EXERCISE ▬▬▬▬▬▬▬▬▬ Show that: 01:03 (∀x≥1),(∀y≥1) ∶ x^2+y^2+xy-x-y-1=0 ⇒ x=y=1 13:54 (∀n∈N) ∶ (2n+1 is a perfect square) ⇒ (n+1 is the sum of two perfect squares) ▬▬▬▬▬▬▬ BRANCHES CONCERNED ▬▬▬▬▬▬▬ 1 bac sm 1 baccalaureate in sex 1 baccalaureate in science and mathematics 1 baccalaureate in physical science 1 baccalaureate in life sciences 1 baccalaureate in experimental science ▬▬▬▬▬▬▬ SUBSCRIBE ▬▬▬▬▬▬▬ 💡👉 Subscribe here:    / @mathphys   ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ 🔔 Please click the LIKE button if you enjoy our content and subscribe to our YouTube channel to receive our new videos. 👉Let me know your questions in the comments section if you don't understand something! 😀 💡Please also remember to SHARE with your friends!!💪💪🔥🔥 ▬▬▬▬▬▬▬ SOCIAL MEDIA ▬▬▬▬▬▬▬   / 536279063660093     / math-phys-112225370317476     / math.phys   ▬▬▬▬▬▬▬ SIMILAR VIDEOS ▬▬▬▬▬▬▬ Mathematical Logic: Implication - Logic - 1 Baccalaureate SM S.EX [Exercise 1]:    • Logique Mathématique - Implication - La Lo...   Mathematical Logic - Logic and Reasoning Course and Exercises - 1 Baccalaureate SM S.EX [Part 2]:    • Logique Mathématique - Cours et Exercices ...   Mathematical Logic - Logic and Reasoning Course - 1 Baccalaureate SM S.EX [Part 1]:    • Logique Mathématique - Cours de la Logique...   ▬▬▬▬▬▬▬▬▬ Video Summary ▬▬▬▬▬▬▬▬▬ The objective of this exercise is to explain the different techniques of Implicational Reasoning. • In the first exercise, we assume the initial proposition is true and start with implications, introducing the beginning of a remarkable identity until we arrive at the required result. • In the second exercise, we assume the initial proposition is true and start with implications, using concepts already covered in the Arithmetic course to arrive at the required result. ▬▬▬▬▬▬▬▬ KEYWORDS ▬▬▬▬▬▬▬▬ #Logic #Math #Implication #MathPhys
